TEST UR MIND

1:it is in a rock but not in a stone.
it is in a marrow but not in a bone
it is in a bolster but not in a bad
it is not living,nor is it dead
WHAT IS IT?

2:they call me a man,but i'll never have a wife
i was given a body,but not given life
they made me a mouth,but didn't give me breath
water gives me life anf sun bring me death
WHAT AM I?

3:only one colour,but not one size:
stuck to me ground,yet easily flies,
present in the sun but no pain.
WHAT IS IT?

4:a littlenool with the two layers of wall around it,
one while and soft and the other dark and hard,
amidst a light of brown grassy lawn with an outline of green grass
WHAT AM I?
